The Ideal Complement to Your Ducted System When It Is Impractical or Prohibitively Expensive to Use Ductwork
• industry-leading features
• 3 types of compact, attractive fan coils for unparalleled flexibility in any room decor
• wide range of accessories available to meet a variety of installation requirements
FEATURES/BENEFITS
UNLIMITED FLEXIBILITY — The new 538S multi-split system
has been designed to provide the utmost in flexibility and
industry-leading features in a multi-zone system. The multi-split
system allows 2-, 3-, or 4-zone operation through the 2 available
condensing unit configurations: a 24,000 Btuh 2-zone system or
a 48,000 Btuh 4-zone system.
These unique systems permit many possible fan coil combinations and incorporate high wall, ceiling suspended, and
in-ceiling cassette fan coil units. The system allows mixed configurations such as one high-wall, 2 in-ceiling cassette, and one
ceiling-suspended fan coil unit all operating from one 538S048
condensing unit.
SOPHISTICATED PERFORMANCE AND SIMPLE DESIGN —
The units have been specifically designed to be simple to install,
easy to operate, and extremely reliable. Each 538S circuit typically supplies 2 zones. When a given zone is satisfied, the
microprocessor signals a solenoid valve to shut off flow to that
zone. The refrigerant flow is then diverted to the active zone until that zone is satisfied. This unique design eliminates the need
for the hot gas bypass function and reduces any chance of improper refrigerant volume or velocity through the system, thus
enhancing performance and compressor life. The units are ruggedly built and can operate down to −20 F when equipped with
the winter start kit. In addition, the multi-split condensing units
use scroll compressors for reliable and efficient performance.
The multi-split system serves as an enhancement to the existing
duct-free split product line by allowing multiple-system projects
to be designed with a minimum number of condensing units.
These systems offer savings in electrical components, installation accessories, and drastically reduced labor time. Savings
are accomplished by centralizing up to 4 zones from one condensing unit. This centralization also permits simplified service
and routine maintenance. Another key benefit of the systems is
a dramatic reduction in sound levels due to the elimination of
Form No. PDS 538S.24.2
of the coil. Coils can be cleaned quickly from the outside using
a pressure hose and detergent without removing grilles or using
fin combs.
The outdoor units also include a microprocessor-based control
board that features expanded diagnostics through multiple LED
(light-emitting diode) displays.
On indoor units, service and maintenance expense is reduced
due to easy-to-change cleanable filters on all units. In addition,
the high wall systems have extensive self-diagnostics to assist
in troubleshooting. All units have easy-access coils and cleanable condensate pans to assist in meeting indoor air quality
standards.
All refrigerant service valves are brass, front-seating type with
sweat connections. The valves are externally located so refrigerant tube connections can be made quickly and easily. Each
suction valve has a service port for ease of checking operating
refrigerant pressures. Internal service ports are also provided to
make servicing even easier.
noise-generating condensing units (one condensing unit per fan
coil unit is required in standard split systems).
AN INEXPENSIVE AND CREATIVE SOLUTION TO DESIGN
PROBLEMS — Multi-split duct-free cooling systems are a
matched combination of a 538S outdoor condensing unit and up
to 4 customer-selected indoor fan coil units connected only by refrigerant tubing and wires. When combined with the 538S condensing unit, the 3 fan coil choices will fit almost any application.
The fan coils can be mounted on the wall, at the ceiling, or in the
ceiling. This selection of fan coils permits inexpensive and creative solutions to design problems such as:
• add-ons to current space (an office or family room addition)
• special space requirements (a computer room)
• when changes in the cooling load cannot be handled by the
existing system (when adding heat-generating equipment to a
currently conditioned space)
• when adding air conditioning to spaces that are heated by hydronic or electric heat no with ductwork
• historical renovations or any application where preserving the
appearance of the original structure is essential
BUILT-IN RELIABILITY — These multi-split system indoor and
outdoor units are designed to provide years of trouble-free
operation.
The high wall indoor units include freeze-up protection, high
temperature protection, and self diagnostics. Other indoor units
are protected by outdoor unit controls and have limited diagnostics available through standard or accessory 24-v thermostats.
The 538S condensing units are the only dedicated commercial
units with all safety features standard to ensure high performance and lasting reliability under the most demanding conditions. For example, an accumulator safeguards the compressor
against loss of lubrication, while capacitors assure dependable
start-ups, especially during low voltage conditions (down to
187 v). High- and low-pressure safety switches, liquid line filter
drier, and lock-out protection are standard.
NOTE: Compressor start-up delay through the controller is
standard for 619C,E,F units.
The 538S unit also has a fan-cycling head pressure control system as a standard feature, which permits cooling operation
down to −20 F (wind baffles and a winter start kit are also
recommended).
The totally-enclosed condenser-fan motor means greater reliability under rainy conditions, ensuring dependable performance for many years.
The compact indoor fan coil units take up very little space in the
room and will not obstruct windows. The fan coils are attractively styled to blend with most room decors. Advanced system
components incorporate innovative technology to provide reliable cooling performance at high efficiencies and low sound
levels.
Duct-free split systems offer the solution of choice. The compressor is located outdoors and is linked by refrigerant lines to
an indoor fan coil located directly in the room it will cool. These
systems have minimal impact on the existing structure, and the
design and interior of the conditioned space is not compromised
by bulky ductwork. Because of these features, duct-free split
systems can be installed in places where conventional ducted
cooling simply cannot go.
LOW SOUND LEVELS — Minimal sound levels are synonymous with the multi-split system. When noise is a concern, the
multi-split duct-free cooling system is the answer because you
don’t have to worry about duct design or the inherent noise associated with ducted systems. There are no compressors indoors, either in the conditioned space or directly over it. The
indoor units are whisper quiet. The outdoor units operate at
sound levels as low as 6.8 bels, and are the perfect answer to
sound level ordinances.
When sound ordinances and proximity to neighbors demand
ultraquiet operation, the 538S is the right choice: The advanced,
horizontal airflow design distributes air more evenly over the
coil. This design reduces local air velocity and a potential source
of noise.
INDIVIDUAL ROOM ZONING FOR OPTIMAL COMFORT —
Maximum comfort is provided because each space can have individual set points and can be controlled based on actual usage.
The air sweep feature provided on high wall and ceilingsuspended systems permits optimal room air mixing to eliminate hot and cold spots to enhance occupant comfort.
In addition, year-round comfort may be provided by combining
standard cooling outdoor units with heat pump versions of some
fan coil units. This combination can provide electric resistance
heating capability.
HIGH EFFICIENCY — With SEERs (seasonal energy efficiency
ratios) of 12.0, the duct-free split systems save energy and may
qualify for utility company rebates in some areas.
SECURE OPERATION — If security is an issue, outdoor and indoor units are connected only by refrigerant piping and wiring to
prevent intruders from crawling through ductwork. In addition,
since 538S units can be installed 6 in. away from outside walls,
coils are protected from vandals and severe weather.
FAST INSTALLATION — These compact multi-split systems
take only a few hours to install, since only wire and piping need
to be connected. The fast and easy installation ensures minimal
disruption to customers in the home or workplace. This is an
added advantage of Carrier’s multi-split systems, especially in
retrofit situations.
ECONOMICAL OPERATION — The duct-free split system design allows individual room cooling only where required. There
is no need to run large supply-air fans or chilled water pumps to
handle a few spaces with unique load patterns. In addition, because air is moved only in the space required, no energy is
wasted moving air through ducts.
Features like the permanent split-capacitor type motors provide
more economical operation, and the rifled copper tube with louvered aluminum plate fin coils provide maximum heat transfer.
SIMPLE SERVICING AND MAINTENANCE — Removing a
single panel on outdoor units provides immediate access to the
isolated compressor and control compartment, allowing a service technician access to check unit operation without a loss of
condenser airflow. In addition, the blow-thru design of the outdoor section means that dirt accumulates on the inside surface
LIGHTWEIGHT, COMPACT SIZE —The small footprint of the
538S units provides additional benefits. Exclusive aeroacoustics make these units the most compact in the industry. Because
they require minimal service and airflow clearances, condensing units can be located virtually anywhere — on the ground,
roof, balcony, or under a deck.
2
AGENCY LISTINGS — All systems are listed with ARI (Air Conditioning & Refrigeration Institute), UL (Underwriters’ Laboratories), CSA (Canadian Standards Association), and CEC
(California Energy Commission).
The outdoor unit can be mounted on any type or weight roof,
and the indoor units take up little valuable, rentable space. Because they are duct-free, not having to run large ductwork
leaves additional space to be rented or utilized, making the
building even more profitable.
In addition, the small size makes these units easily moveable.
When floor plans change, the units can be quickly reinstalled.

CHARCOAL FILTER KIT
The charcoal (carbon) filter kit is available for duct-free high wall fan
coil units. This accessory improves indoor air quality by removing
volatile organic compounds (VOCs), odors, and micro-particles from
the air. The filter kit can be installed either before or after the unit has
been mounted to the wall. Filters must be changed approximately
every 3 months.

POWER VENTILATION KIT
Power ventilation kit provides for up to 10% outdoor air intake capability for the in-ceiling cassette (619F) units and up to 30% capability
on ceiling-suspended (619C) units. The filter is mounted at the fan
coil unit and filters the outdoor air. A booster fan with speed control
is provided to allow for long duct runs and to balance airflow to the
unit for consistent unit operation.
NOTE: When kit is used on 619C units, fresh air intake kit is also
required.

CONDENSATE PUMPS
Condensate pumps provide condensate lift capability of 20 in. on
ceiling-suspended (619C) fan coils.
On high wall fan coils, condensate pump has a lift capability of approximately 3 to 25 ft (018,024 units). See the chart below.
The pump mounts inside the unit with quick plug-in connections, and
is recommended when adequate drain line pitch cannot be provided.
NOTE: This pump is standard on the in-ceiling cassette (619F) fan
coils, where it provides a lift capability of 20 in. above the condensate pan.

FRESH AIR INTAKE KIT
Fresh air intake kit provides for a variable amount of outdoorair capability for the ceiling-suspended (619C) and cassette
(619F) fan coils. Up to 30% outdoor-air can be supplied to
619C units and up to 10% can be supplied to 619F units. The
filter is mounted at the fan coil unit and provides filtering of
outdoor air before it enters the unit. (Ceiling-suspended system application is shown.)

ACCESSORIES (Field Installed) (cont)
FAN COIL UNITS
Indoor guard is a decorative wire guard for the ceilingsuspended (619C) fan coils. The guard mounts over the fan coil
discharge to prevent objects from entering the unit and air
sweep.
Electronic programmable thermostats are available for inceiling cassette (619F) and ceiling-suspended (619C) fan coils.
These commercial-grade thermostats provide 7-day, 4-eventper-day scheduling. The included subbases provide 3-speed
fan switchover capability.
CONDENSING UNITS
Winter start control is a single-pole, single-throw delay relay
that bypasses the low-pressure switch for approximately 3 minutes at unit start-up. The control permits start-up for cooling operation under low load conditions at low-ambient temperatures.
This accessory is recommended on all 538S systems to provide
cooling at outdoor ambient temperatures below 40 F.
Crankcase heater accessory is a clamp-on compressor oil
sump heater. This heater is necessary wherever unit operation
in cooling is anticipated at outdoor ambient temperatures under
40 F.

SELECTION PROCEDURE (With Example)
capacity [(19,400 - 14,700) × (4/5) + 14,700]. Adjust the
SHG in accordance with Note 2 of the Cooling Capacity
table, using the correction factor for an 82 F edb (air entering dry bulb), and an 0.17 BF (bypass factor). The result
is an adjusted SHG of 20,339 Btuh. The total gross cooling
capacity of 24,000 Btuh and the sensible heat capacity of
20,339 Btuh satisfy stipulated cooling load requirements.
I DETERMINE THE TYPE OF FAN COIL WHICH BEST
SUITS THE APPLICATION (REFER TO SYSTEMS INDEX TABLE ON PAGE 21):
Duct-free split systems have 3 types of fan coils to choose
from with overlapping capacities. Select the system type
which best meets the job conditions. This example will use
one 11⁄2-ton high wall fan coil and one 11⁄2 ton in-ceiling
cassette.
V DETERMINE NET COOLING CAPACITY AND SYSTEM
ENERGY EFFICIENCY RATIO:
Determine net cooling capacity (refer to Cooling Capacity
table no. 5 on page 27). Net total cooling capacity must be
interpolated as follows:
(24,900 - 23,000) x (1/5) + 23,000 = 23,380 Btuh
To determine the energy efficiency ratio (EER), system kW
must be interpolated from Cooling Capacity table no. 5 in
the same manner:
(2.15 - 2.14) x (1/5) + 2.14 = 2.14 kW
Then calculate EER:
Net Cooling Capacity
EER =
kW x 1000
23,380
= 10.9 EER
2.14 x 1000

LOAD
REQUIREMENTS:
Enter the Systems Index table on page 21 at systems for
24,000 Btuh, and select the system that best approximates
cooling requirements. System index no. 5 with a nominal
net capacity of 23,000 Btuh cooling is the system selected.
The system consists of a 538S024 outdoor unit matched
with one 619E018 and one 619F024 indoor unit.
NOTE: The SEER (Seasonal Energy Efficiency Ratio)
CANNOT be calculated for this system. SEERs can only
be found as a direct result of testing at specified ARI conditions. See ARI Capacities table on page 6.
IV DETERMINE IF SYSTEM SELECTED SATISFIES
COOLING REQUIREMENTS:
Enter Cooling Capacities table no. 5 on page 27 at high
speed and 95 F outdoor entering air temperature (air entering condenser). By interpolation, at 68 F EAT, the system gross capacity is 24,000 Btuh cooling [(25,600 23,600) × (1/5) + 23,600], and 18,460 Btuh gross sensible

NOTES:
1. If a system consists of 2 fan coil units on each circuit (using a
558S048 condensing unit), and one fan coil unit is turned off, the resulting system capacity will change. For example, for system option
no. 17 in the table on page 22, with all fan coil units turned on
and available for cooling, system capacities are determined using
cooling capacity table numbers 1 and 2. If one of the 619F024 fan
coil units is turned off (not available for operation), the new system
capacity would be derived using cooling capacity tables 2 and 8
(43,400 Btuh). Contact your local representative for assistance with
your specific application.
2. Tables 7, 8, and 9 show system performance with one fan coil running in a circuit designed for two fan coils. Using any of these units
by themselves as the only fan coil on a circuit is not recommended.
Performance data is provided for reference only.

*Option numbers correlate to unit Price Page options. Contact your local representative for more details.
†Btuh capacity ratings describe fan coil unit combinations as listed in
the Indoor Section column above.
**Cooling capacity table numbers reference tables on pages 23-34.
When more than one table is referenced, add together the capacity
data listed in each table for the system total capacity. This procedure
is also appropriate for determining total system power and total compressor power.
††Unit must be field reconfigured for 18,000 Btuh operation. Refer to installation instructions included with fan coil unit for more details.

APPLICATION DATA
2) CEILING-SUSPENDED UNITS — These units
should be mounted near the ceiling and against a
wall. The unit should be centered (horizontally) on
the wall for best performance. Locating the unit on an
outside wall will make piping easier, but units can
also be mounted away from a wall if desired. (If the
unit is mounted away from a wall, the rear panel of
the unit may need a field-supplied trim strip for improved appearance.) For quietest operation, locate
the fan coil return over an area which is not normally
occupied. Do not block air discharge for a minimum
of 15 ft to prevent dumping of cold air and drafts.
3) IN-CEILING CASSETTE UNITS — These units
should be mounted in the ceiling, preferably near the
center of the room. If the unit must be mounted near
a wall, close the air discharge on the blocked side(s).
(Up to 2 sides may be blocked.) Locate the control
box away from the blocked side(s).
1. Unit selection
Select equipment so that capacity either matches or is
slightly less than anticipated peak load. This provides better
humidity control, fewer unit cycles, and less part-load
operation.
For units used in spaces with high sensible loads, base
equipment selection on unit sensible load, not on total anticipated load. Adjust for anticipated room wet bulb temperature to avoid undersizing equipment.
When selecting equipment that has outdoor air introduced
into the unit, determine the mix conditions of room air and
outdoor air at design conditions. The cooling capacity
tables in this literature are based on 80 F edb. Adjust for actual entering dry-bulb and wet-bulb conditions of the required outdoor air to select the proper equipment.
2. Unit combinations and coil mixed matches
The 538S units are the only units approved for use with the
619C, E and F multi-split systems. The 538S units can also
be used with other fan coil units.
Mixed matches of indoor-fan coil capacity are not recommended except as listed in Systems Index Table on
page 21.
Heat pump fan coils can be used with cooling-only condensing units to provide electric heat capability.
5. Mounting template
The 619C fan coil units are furnished with a mounting template to mark the location of the mounting brackets, wiring,
and refrigeration hole locations. In addition, the 619C units
indicate the location of ventilation-air connections.
6. Support
Adequate support must be provided to support the weight
of all fan coils. Refer to the Physical Data section on
page 11 for fan coil weights, and the base unit dimensional
drawings on pages 15-19 for the location of mounting
brackets.
3. Unit mounting (outdoor)
a. Unit leveling — For reliable operation, units should be
level in all planes.
b. Clearance — Adequate clearance must be provided for
airflow. See dimensional drawings for proper clearances. The condensing units are designed for free-blow
application. Air inlets and outlets should not be restricted. Outdoor fan external static pressure available is
less than 0.1 in. wg.
c. Unit location — Cooling units can be stacked 2 high.
Units can be wall mounted, pad mounted at ground
level, roof mounted, or mounted on a deck or patio. Be
sure water drainage from roof will not drain directly onto
the unit.
NOTE: If stacking units, field-fabricated and installed hardware is required. Contact your local representative for
drawings and details.
If 538S condensing units are being mounted near a wall,
the condenser air should discharge toward the wall. This
position provides inherent coil protection and the best possible sound and airflow performance.

4. Unit mounting (indoor)
a. Unit leveling — For reliable operation, units should be
level in all planes. The 619C ceiling-suspended fan coils
may have a slight pitch, but only toward the drain
connection.
b. Clearance — Provide adequate clearance for airflow.
The unit return and discharge should not be obstructed
by furniture, curtains, or anything which may cause unit
short cycling or air recirculation. See base unit dimensional drawings on pages 15-19 for required clearances.
c. Unit location — When selecting unit location, select a
location which provides the best air circulation for the
room.
1) HIGH WALL UNITS — These units should be positioned as high as possible on the wall for best air circulation. Allow adequate clearances above the unit
for servicing (removing unit covers). If possible, place
the unit in the middle (horizontally) of the wall selected. Select an outside wall (if available) to make
piping easier, and place the unit so it faces the normal location of room occupants.

Units can operate in cooling mode down to 55 F under all
conditions.
Units intended for operation in cooling mode below 40 F
should also be equipped with accessory crankcase heater,
accessory winter start kit, and field fabricated and installed
wind baffle.
a. Winter start (accessory) — Winter start bypasses the
low-pressure switch for 3 minutes. Use when cooling operation in outdoor ambient temperatures below 40 F is
anticipated.
b. Crankcase heater (accessory) — Use when cooling
operation at outdoor ambient temperatures below 40 F
is anticipated.

should be buried. Provide a minimum 6-in. vertical rise
to the service valves to prevent refrigerant migration.
c. Both liquid vapor lines must be insulated. Use a minimum of 1⁄2-in. thick insulation. Closed-cell insulation is
recommended in all long-line (over 25 ft) applications.
d. Special consideration should be given to isolating interconnecting tubing from the building structure. Isolate the
tubing so that vibration or noise is not transmitted into
the structure.
538S Units:
a. The 538S units are shipped with a full charge of R-22 refrigerant. Charge is based on 25 ft of line.
b. Filter driers are provided in the unit.
c. Two-phase supply lines on all 538S units should be 3⁄8
in. only. DO NOT resize supply lines for additional
length.
d. Vapor return line size is 5⁄8 in. for all applications.
9. Drain connections
Install drains to meet local sanitation codes. If adequate
gravity drainage cannot be provided, unit should be
equipped with accessory condensate pump. High wall fan
coil unit accessory condensate pumps have a 3 to 25 ft lift,
and all other fan coil units have a lift capability of 20 in.
above the condensate pan level.
See base unit dimensional drawings on pages 15-19 for
drain locations and sizes.
NOTE: High-wall fan coil units have internal condensate
traps. All other fan coil units require a field-supplied external
condensate trap.
Drain connections can be routed through alternate locations on most fan coils. See base unit dimensional drawings
on pages 15-19 for possible alternate locations.
Electric heat — The under-ceiling cooling systems can
provide electric heat by using the heat pump version of the
fan coil unit. Also, any unit with a condensate pump must
have a jumper wire installed between terminals O and Y on
the fan coil unit low-voltage terminal strip. Refer to the heat
pump Product Data literature for appropriate fan coil electrical data.
11. Controls
The 619E fan coil units are controlled by wireless remote
controls. The 619C and 619F fan coil units must be hardwired only.
Wired 24-v Controllers (619C, 619F)
a. A 24-v thermostat is supplied for operation of all inceiling and cassette systems.
b. Controller can only operate one unit, and a controller is
required for each unit.
c. The control must be located in the space being
conditioned.
10. Refrigerant lines
General refrigerant line sizing:
a. All charges, line sizing, and capacities are based on
runs of 25 ft. For runs over 25 ft, consult 538S Units section on this page for proper line sizing and charge.
NOTE: For runs less than 25 ft, some of the charge may
need to be removed to obtain the correct system superheat. The minimum line length should be 8 ft.

16. Fresh air/ducting
a. The 619C ceiling-suspended fan coil units may bring in
up to 30% fresh air. The percentage of air allowable is
calculated based on the unit high speed airflow. Air
quantities above this level may exceed compressor
maximum saturated suction temperatures. A power ventilation kit is available to overcome ventilation duct static.
See Power Ventilation Kit Available Static table below.
b. The 619F in-ceiling cassette fan coil units may bring in
up to 10% fresh air. This 10% maximum should not be
exceeded. A power ventilation kit is available to overcome ventilation duct static. See Power Ventilation Kit
Available Static table below.
c. The 619F in-ceiling cassette fan coil units may have an
extension duct installed. See Static Capability and
Design Considerations figures on page 42.
12. Group control
The 619C and 619F fan coil units may be group controlled
from a single timeclock or energy management system by
interrupting the 24-v power to the control board. See system wiring books for details.
13. Thermistor
The 538S unit has one thermistor that monitors entering-air
temperature at the condensing unit. The 619E unit has 2
different thermistors mounted at the indoor unit. The indoor
unit thermistors are not monitored at the 538S outdoor unit.
14. Wiring
Use only copper wires from the disconnect to the unit terminal block. Aluminum and copper-clad aluminum wires are
not acceptable.
All multi-split systems provide 24-v power for the outdoor
unit in the fan coil unit.
All systems should have a separate disconnect for each indoor and outdoor unit.

CONTROLS
The microprocessor control in the 538S unit includes a
2-minute, anti-short cycle, time-delay function. This function
provides a minimum off delay between compressor run stages
(2 minutes each from the end of the last on period to the beginning of the next on period). If more than 2 minutes have passed
since the end of the last on period, the compressor is ready to
restart with initiation of demand from any fan coil unit on its
circuit.
Increased Demand for Cooling
NOTE: There are 2 separate compressor circuits in the
538S048 units (circuit A and circuit B). Each circuit operates independently, and will operate as follows (as will the singlecircuit 024 units) upon receiving the first 24-v cooling demand
signal from a fan coil unit:
UNIT OPERATION
NOTE: AUTO fan mode is used as the unit operation example
for ALL fan coil units in this section. Contact your local dealer for
operation information in other fan modes.
Fan coil units — Each fan coil unit has a self-contained control
system that determines the set point for fan coil operation, fan
mode operation, and heating mode operation (if provided). The
fan coil units are equipped with either a wired or wireless remote
controller set. Set points and fan modes may be determined
separately for each fan coil unit.
Each fan coil unit may call for cooling operation independently.
On a call for cooling operation by a single fan coil unit, a 24-v
signal is sent to the 538S outdoor unit and energizes a control
relay. The indoor blower starts according to the normal fan coil
unit sequence of operation. The control relay (in the outdoor
unit) initiates operation of a cooling cycle for the respective indoor unit refrigerant circuit; including opening a liquid line solenoid valve in the outdoor unit.
As the set point at each fan coil is satisfied, its individual 24-v
signal to the 538S unit stops, and the respective solenoid valve
for each fan coil unit closes. The indoor fan cycles off. The 619E
fan coil units then begin room sampling operation after a
3-minute off period (during sampling, the fan motor runs at low
speed for 1 minute to sample the demand in the space; then
cycles off until the next sampling period if no demand is found).
538S outdoor condensing unit — The outdoor unit is
equipped with a control that monitors the indoor fan coil cooling
request. The control turns on solenoid valves for the appropriate
indoor fan coil unit system. The control also combines the cooling requests to control up to 2 compressors.
The 538S control provides a 2-minute compressor time-delay
circuit which disables the compressor for 2 minutes at unit startup. The time delay device timers are initialized when the unit is
powered up (for the first 2 minutes).
The 538S unit control includes an integral head pressure control
function. This function maintains a minimum head pressure by
cycling the outdoor-fan motor in response to inputs from the
thermistor (for outdoor ambient temperature) and the transducers (for system discharge pressures in each compressor
circuit).
The head pressure for the compressor(s) is monitored to control
the outdoor fan output. The control reads an outdoor temperature thermistor to determine if the head pressure should be used
to control the fan output.
Operation — The 538S unit receives a 24-v control signal from
each fan coil unit as each fan coil unit initiates a demand for
cooling. The 24-v signal energizes a control relay in the 538S
unit (one relay per fan coil unit). The refrigerant flow to each fan
coil unit is controlled through a solenoid valve (one valve per fan
coil unit). The solenoid valve(s) will not open until compressor
operation is initiated by the controller.
1. After the 2-minute time-delay function is satisfied, the appropriate compressor starts.
2. The solenoid valve connected to the fan coil sending the demand signal is energized (at the 538S units).
3. The outdoor fan starts, and its operation is controlled by the
microprocessor as described in 538S Microprocessor Control of Outdoor Fan section below.
When a second fan coil unit signals a demand for cooling, its associated solenoid valve is energized immediately, allowing refrigerant to flow to both fan coil units simultaneously.
Decreased Demand for Cooling — When a fan coil unit’s demand for cooling ends, the 24-v signal to the 538S unit stops,
and the appropriate solenoid valve closes. If the other fan coil
unit on this circuit still has a demand, the appropriate compressor continues to run as long as necessary for the second fan coil
unit.
When the second fan coil unit’s demand for cooling ends, its solenoid valve closes, and the appropriate compressor stops. The
compressor will not start for at least 2 minutes after the end of
this cycle due to the time-delay function.
On size 024 units, when the compressor stops, the outdoor fan
also stops. On size 048 units, outdoor fan operation may continue under control of the 538S microprocessor if the other refrigerant circuit is still operating. The outdoor fan only stops
when both compressors are off. Refer to 538S Microprocessor
Control of Outdoor Fan section below for more details.
538S microprocessor control of outdoor fan — The microprocessor control has a built-in head pressure control system
that cycles the outdoor-fan motor to maintain a selected discharge pressure. The microprocessor senses outdoor ambient
temperature using a thermistor and refrigerant pressure using a
pressure transducer mounted on the compressor circuit discharge line. The 538S024 units have one transducer, and the
048 units have two.
The factory set points for the head pressure control operation
are 55 F for outdoor ambient temperature and 250 psig for discharge pressure.
48
CONTROLS (cont)
Also see System Status Red and Green LEDs and Fault Codes
table below.
When the outdoor ambient temperature is above the outdoor
ambient set point and both fan coils on a compressor circuit are
calling for cooling operation, the outdoor fan runs at full speed
whenever compressor operation is permitted. When only one
fan coil is calling for cooling, fan cycling is permitted at all ambients. Fan motor is then cycled on and off to maintain set point
discharge pressure.
When the outdoor ambient temperature is below the specified
set point, the fan motor is cycled on and off to maintain a compressor discharge pressure at the specified pressure set point.
On 538S048 units with 2 compressors running, the compressor
with the lower head pressure controls the fan operation. If only
one compressor is running, that compressor controls the fan
operation.
If the discharge pressure on either circuit exceeds 370 psig, the
outdoor-fan motor runs continuously, and the fan cycling function is bypassed until the discharge pressure decreases to
365 psig.
Units can be field configured to select head pressure control at
35 F outdoor ambient and/or 200 psig discharge pressure.
Unit malfunction — Each compressor circuit is equipped with
a high-pressure switch (HPS), a low-pressure switch (LPS), and
a discharge temperature switch (DTS). These safety devices
are located in a Cycle-LOC™ device circuit that prevents compressor operation if any of these safety devices is activated. The
lockout can be reset by turning the main power to the 538S unit
off, then on again.
Compressor overcurrent protection is achieved by an internal
linebreak overload, which automatically resets when the motor
temperature cools to a satisfactory level. Manual reset of CycleLOC circuit may also be required.
Pressure transducers and the outdoor ambient thermistor are
monitored by the 538S controller. If a pressure transducer is
found to be out of range, the LEDs flash a code for this fault, but
the control continues to cycle the outdoor fan according to input
from the other transducer. If only one transducer is active and is
determined to be out of range, the head pressure control is bypassed and the fan runs continuously. If the thermistor is found
to be out of range, the control allows fan cycling per transducer
input, and the LEDs flash a code for this failure. See System
Status Red and Green LEDs and Fault Codes table below for
diagnostic codes.
Status indicator lights — The 538S control board is equipped
with LED indicators to aid in evaluating the status of the control
system, including:
